Question

the ratio of copper and zinc in an alloy is 9 : 5 if the weight of copper in the alloy is 48.6g find the weight of zinc in the alloy ​

Answer 1

Answer:

27

Step-by-step explanation:

let the weight of copper be 9x and the weight of zinc be 5x, so 9x=48.6g(given),we need to find the value of x. so x=48.6÷9=5.4,now we multiply the value of x with 5 as to find the value of 5x,that is the weight of zinc, so value of x multiplied by 5= 5.4×5=27,hence the ratio of zinc in an alloy is 27.
